Pachicom
is a parlor video game released for multiple platforms that is themed around pachinko. It was released in 1985 exclusively to the Japanese market.
The game of pachinko is hugely popular in Japan, since it involves playing pinball with an element of slot machines mixed in along with gambling. There are four different gameplay modes to choose from (two of them assign a player with a pachinko machine while the other two allow players to choose their own machine).
